EMBOSSlNG-DIE FOR BURNlSHlNG-ROLLS.

SIECIFIGATION forming part of Letters Patent No. 628,593, dated July 11,1899.

Application filed April 2 9, l 8 9 9 To all whom it may concern:

Be it known that I, EDWIN H. WILKINSON, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Embossing-Dies for Burnishing-Rolls; and I declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

My invention relates to means for fixing an imprint upon photographicmounts or other cards; and it consists in an attachment to one of therolls of an ordinary burnishing-machine. v

In the drawings, Figure 1 represents a burnishing-machine with myattachment in position. Fig. 2 is a perspective view of the at tachment.Fig. 3 is a cross-section of the same.

Referring to the letters of reference on the clrawin gs, A is theburnisher, and B one of the rolls.

0 is a die formed in two parts, as shown, and secured around the roll bythe pins 0 0 entering suitable orifices arranged to register when theparts 0' and O are brought together.

D is a set-screw iaving a bearing in the part 0 and when the parts 0'and C are arranged to embrace the roll is adjusted so as to bear againstthe roll, and thus fix the die firmly in position. 1

E is an adjustable guide or register mounted on the die and is securedto the same bythe Serial No. 715,051. (No model.)

, set-screws e e entering the die through slots in the guide.

The operation of the device is as follows: The die being properlysecured to the roll and the guide E adjusted so as to leave the imprintupon the card at the point desired, the mount is placed between therolls and the same are rotated so as to impress the imprint upon thecard,which is then removed.

Of course many 'ways of securing the die to rolls will suggestthemselves, and I therefore do not wish to limit myself to the formshown, though it is considered a desirable one; but

What I do wish to claim and secure by Letters Patent is- V 1. Thecombination of a burnishing-roll and a die, substantially as described.

2. The combination of a burnishing-roll, a die,.and means for securingthe same to the roll, substantially as described.

3. A die formed in semicircular parts, said parts made to interlock, andmeansfor securing the same to a roll substantially as described.

l. Adie formed in semicircular parts, said parts made to interlock and aset-screw for securing the same to a roll, substantially as described.

5. The combination of a burnishing-roll, a die, means for securing thedie to the roll and an adjustable gage,substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.
